Mystical Realms Modpack Fixes

v1.2.0 - Better Party member-health crash guard

Adds a new optional, server-side compatibility patch for Better Party. Same compatibility-patch philosophy as the rest of this mod: it never touches the affected mod's jar, and the patch only activates when that mod is present.

Added

• Better Party member-health crash guard: BetterPartyServerApi.memberHealth(ServerPlayer) falls back to new PartyMemberHealth(player.getHealth(), player.getMaxHealth()) whenever no custom health-provider add-on is registered. That record's constructor throws an uncaught IllegalArgumentException if either value is non-finite or maxHealth <= 0, which propagates out of BetterParty#onServerTick and crashes the entire dedicated server mid-tick — for every player online — the instant a single player's generic.max_health attribute gets corrupted, even momentarily. New soft, server-only mixin BetterPartyMemberHealthGuardMixin (gated by BvaMixinPlugin on better_party actually being loaded) wraps the two vanilla ServerPlayer accessor calls that feed the record and substitutes a safe finite value if either reading is currently invalid, logging a warning instead of crashing.

Notes

This patch stops the crash, it does not fix whatever corrupts the player's generic.max_health attribute in the first place — if it keeps happening, look at what other mod/enchantment is stacking attribute modifiers on that player around the same time. Optional dependency on better_party (server side). No new compile-time dependency was added to build this mod: the target class is referenced by name only (@Pseudo soft mixin target), never on the compile classpath. Verified: ./gradlew clean build is green.
